Issue with UART/USB Rx interrupt in STM32F407VGT6 and using DP83848 LWIP stack.

[Satya_VVM]

Hello, Good morning all,

I am doing a project with STM32F407VGT6 and DP83848 Ethernet Controller using LWIP stack. My requirement is UART/USB to Ethernet. I have enabled global interrupt and IRQ Handlers for both USB & UART, but when I send data from UART/USB RX interrupt is not enabling by MCU. Please suggest me the solution to enable USB/UART interrupt for receiving data.

Thanks and regards

Hello @Satya_VVM 

Are you sure there is a data transfer on the bus ? Could you please check the trafic on the bus using logic analyser ?
